Tyrosine is a non essential white crystalline amino acid (C9H11NO3) with an uncharged polar side chain. Its three letter code is Tyr and its single letter amino acid code is Y. Its side chain consists of an aromatic ring and a hydroxyl group which is polar [1]. It's formed from the hydrolysis of proteins for example, casein. It is also a precursor for epinephrine, thyroxine and melanin [2].
